The Trump administration move to study aluminum in vaccines worries scientists

The Trump administration is taking a closer look at aluminum salts — a key ingredient in many vaccines for nearly a century — and that’s raising alarm among public health experts. Aluminum helps vaccines work better by strengthening the immune response, and scientists say it’s been proven safe through decades of research. But vaccine skeptics inside the administration are pushing for its removal, a move experts warn could weaken vaccines, delay new development, and risk the return of once-controlled diseases.
